    • CR2025: Suited for applications where a slimmer profile is necessary and lower power demands are sufficient.
  5. Duration of Use:

    • CR2032 batteries generally last longer than CR2025 batteries due to their higher capacity and energy output.
  6. Compatibility:

    • Both batteries share the same diameter and voltage (3 volts), making them somewhat interchangeable. However, the thickness difference can affect fitment in certain devices designed specifically for one type over the other.
  7. Cost and Availability:

    • Both CR2032 and CR2025 batteries are commonly available and cost-effective, with widespread use in various electronic devices.
  8. Fitment:

    • While the diameter is the same, the difference in thickness can impact how well a CR2032 fits in a slot designed for a CR2025. In some cases, the extra thickness may cause issues with the battery compartment.

Understanding these differences can help you choose the right battery type based on your device's requirements for power, size, and longevity.
